Some help identifying a bag?

This could be a long shot...but I'm hoping somebody can help me out here.

I was in a consignment store today and saw the most beautiful Chanel bag. I'm about 99% sure it's authentic, but don't want to buy it until I'm 100% sure. This would be my first Chanel, so I don't know a whole lot about them. I just thought if someone knew the style of the bag, it would help to authenticate it. Who knows, maybe it's a style that doesn't even really exist!

It was a white bag and quite structured - not floppy, and there was no flap. It was a tote style bag, the handles were silver chain with white leather at the tops, the part that rests on your shoulders. There were black c's in the middle/lower part of the bag. The leather was very, very soft and if I remember correctly the corners on the bottom had a large, quilted area. I think the top part was also quilted, but I could be making that up.

I hope that makes sense and somebody has an idea what I'm talking about!
